GW170104 – LIGO Detects Gravitational Waves for the Third TimeFirmly transiting into the era of Gravitational Wave Astronomy

Detection of GW170104

On January 04, 2017 at 03:42PM IST the LIGO detectors in Hanford, Washington and Livingston, Louisiana detected a signal from the coalescence of two black holes, with masses 31.2 and 19.4 times the mass of the sun, merging into a more massive, rapidly rotating black hole that is 48.7 times the mass of the sun. The event happened nearly 3 billion years ago, lasted in LIGO's frequency band for about a second and released about 2 solar mass worth of energy in that short period.
